Chrysanthemum plant named ‘Girona Orange’

ABSTRACT

A new and distinct cultivar of  Chrysanthemum  plant named ‘Girona Orange’, characterized by its compact, upright, outwardly spreading and rounded plant habit; freely branching habit; dense and full plant habit; uniform, freely and early flowering habit; and decorative-type inflorescences with orange-colored ray florets.

Botanical designation: Chrysanthemum×morifolium.

Cultivar denomination: ‘GIRONA ORANGE’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Chrysanthemum plant, botanically known as Chrysanthemum×morifolium, and hereinafter referred to by the name ‘Girona Orange’.

The new Chrysanthemum is a naturally-occurring whole plant mutation of Chrysanthemum×morifolium ‘PPP GIRO 09’, disclosed in U.S. Plant patent application Ser. No. 12/462,274. The new Chrysanthemum plant was discovered and selected by the Inventor as a flowering plant from within a population of plants of ‘PPP GIRO 09’ in a controlled greenhouse environment in Oostnieuwkerke, Belgium in August, 2004.

Asexual reproduction of the new Chrysanthemum plant by vegetative cuttings was first conducted in a controlled greenhouse environment in Oostnieuwkerke, Belgium in January, 2005. Asexual reproduction by cuttings has shown that the unique features of this new Chrysanthemum plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Chrysanthemum have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Girona Orange’. These characteristics in combination distinguish ‘Girona Orange’ as a new and distinct Chrysanthemum cultivar:

-   -   1. Compact, upright, outwardly spreading and rounded plant         habit.     -   2. Freely branching habit; dense and full plant habit.     -   3. Uniform, freely and early flowering habit.     -   4. Decorative-type inflorescences with orange-colored ray         florets.

Plants of the new Chrysanthemum differ primarily from the parent, ‘PPP GIRO 09’, in ray floret color as plants of ‘PPP GIRO 09’ have purple-colored ray florets.

Plants of the new Chrysanthemum can be compared to plants of Chrysanthemum×morifolium ‘Denise’, disclosed in U.S. Plant Pat. No. 8,178. In side-by-side comparisons conducted in Oostnieuwkerke, Belgium, plants of the new Chrysanthemum differed from plants of ‘Denise’ in the following characteristics:

-   -   1. Plants of the new Chrysanthemum were more compact than plants         of ‘Denise’.     -   2. Stems of plants of the new Chrysanthemum were more flexible         than and not as brittle as stems of plants of ‘Denise’.     -   3. Plants of the new Chrysanthemum had smaller inflorescences         than plants of ‘Denise’.     -   4. Ray floret color of plants of the new Chrysanthemum was         lighter in color than ray floret color of plants of ‘Denise’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph illustrates the overall appearance of the new Chrysanthemum plant. This photograph shows the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Chrysanthemum plant. The photograph comprises a side perspective view of a typical flowering plant of ‘Girona Orange’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations and measurements describe plants grown in 19-cm containers in an outdoor nursery in Oostnieuwkerke, Belgium during the summer and autumn under conditions and practices which approximate those generally used in commercial production. During the production of the plants, day temperatures ranged from 25° C. to 30° C. and night temperatures ranged from 15° C. to 20° C. Plants were 15 weeks old when the photograph and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2005 Edition, except where general terms of ordinary dictionary significance are used.
